SASH-LOCK.

Specification of Letters Patent.

Patented May 13, 1919.

Application filed August 25, 1916. Serial No. 1,16,890.

To all whom it may concern:

Be it lmown that I, JOHN A. Jones, a citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Sash-Locks, of which the following is a specification.

This invention has relation to window sash locks and the nature and objects thereof will be readily apparent to those skilled in the art to which it appertains in the light of the following explanation, of the accompanying drawings, illustrating what I now believe to be the preferred embodiment or mechanical expression, of my invention from among other forms and arrangements, within the spirit thereof or the scope of the appended claim.

However, an object of the invention is to provide a sash lock including correlated members adapted to be secured to each sash for cooperation to lock the sashes against relative movement. 1- 7 Another object of the invention is to provide a sash lock of the character described adapted to lock the sashes against relative movement subsequent to adjustment in any position relative to each other or to the window frame, and to bind the sashes against the window frame to prevent rattling of the sashes in any adjusted position.

A still further object of the invention is to provide a sash lock of the character set forth, adaptedto be disposed adjacent the sides of the sashes, and embodying means for locking the sashes against relative movement, and resiliently compensating for differences in width of sashes and other details of construction, thereby enabling the device to be used on windows of various types. m

A still further object of the invention is to provide a sash lock of the character set which is adapted to lock the sashes against movement relative to each other in anyrelatively adjusted position thereof, and to further lock the sashes simultaneously against movement relative to the window casing, in any relative adjusted position of said sashes relative to said window frame.

In addition to the foregoing my invention comprehends improvements in the details of construction and arrangement of parts to be hereinafter more fully described and particularly set forth in the appended clalm.

In the accompanying drawings in which similar and corresponding parts are designated by the same characters of reference throughout the several views in which they pp i Figure l, is a fragmentary view in front elevation of window sashes illustrating the pppilication thereto of my improved sash Fig. 2, is a'sectional view partly in elevation taken through the meeting sashes of a window illustrating further the application andrelationthereto of the members of my improved sash lock.

Fig. 3, is a horizontal sectional view taken on the line 3-3 of Fig. 1, and

Fig. 4, is a similar view on line l-4 of Fig. 1.

Fig. 5, is a view in transverse section taken centrally through the device.

In the accompanying drawings, 10 and 11 indicate respectively the lower and upper sashes of a window guided in outer and inner guiding strips 12 and 13 respectively and separated by means of parting strip 14.

The upper sash 11 is provided upon the inner face of one of the vertical side members with a vertically extending rack bar 15, having apertured terminals 16 through which suitable threaded fastenings 17 pass to secure said rack bar to the sash.

. The locking member of my sash lock, is mounted upon the upper edge of the lower sash and comprises a casing 18 flanked at either side by apertured ears 19 through .which suitable threaded fastenings 20 pass to secure the casing to the sash. The casing is substantially semi-circular with the diametrical portion facing the outside of the Window. The casing 18 is provided substantially centrally in its top platewith an opening 21. A locking plate 22 is superposed above and exteriorly of the casing and comprises a discous member having an eccentrieally disposed square opening 23 through which the squared shank 24: of a bolt passes, the said bolt having a hemispherical head 25. Along the diametrical sides of the casing are V formed two inwardly extending lugs 26 loshorter lug 27 sideof the casing also has a short lug 27 as "members 29 are cated near the ends of the casing and a between them. The curved best seen. in' Fig. 4, and thus the two lugs 27 project toward each other. Lugs 28 are V The terminals of one spring member are adapted to rest against the lugs 26, the terminals of the opposite spring member resting against shoulders 30, formed within the casing, the'terminals of the springs being thus brought adjacent one another to place In this position same being shown in :Fig. 3, the opposing faces of the squared shank will bear against the spring members 29 and the shank shifted sis tobe .the springs under tension and more firmly the bolt.

press them against the squared shank of A'rectangular washer 32 is held between the lugs 28 and engaged against thelugs 27 whereby to hold said washer against rotation. The washer is formed with a transversely elongated opening 31 to receive the lower end of the shank 24 which is reduced and rounded to enter said opening. Thereduced end of the bolt subsequent to its insertion in the washer is then upset to prevent-separation of the washer and shank.

The locking. member just described is 'lo- .cated upon the top rail of-the lower sash in close proximity to the rack operation therewith. V

.The construction of my invention having been described indetail, its operation may bar 15, for co- :be briefly stated as follows: The sashes are moved relatively to each other to provide an opening at the top or bottom of the window as the casemay be. revious to such movement of the sashes however, the locking plate rotated by means of an integrally formed finger piece 33 sons to retain the plate out of the path ofmovement of the rack bar 15, or vice versa. Subsequent to adjustment of the sashes in proper relation,

the locking plate 22 is rotated by means of its handle so as to dispose its peripherv in between two of the teeth of the rack bar 15. of the locking plate, the

of the bolt 24 will thusb'e held resiliently in its position. Obviously disengaged from the rack bar'15 it is rotated in aconverse direction, whereupon the. spring'members 29' are 7 rated "by, engagement of the corners of the squared'shank of the bolt .oontinued rotation of the plate and conselugs projecting when the plate slightly sepatherewith, and

quently the squared shank of the bolt brings the opposite faces of said shank again into engagement with the spring members whereupon the locking plate is resiliently held in its newly adjusted position.

Thus it will be seen that the sashes may be held or locked together in any position relative to each other, and within limits of the .Thus, a double locking of the sashes is provided, namely,

relative to each other, and relative to the window frame. Owing to this arrangement, the upper sash for instance, may be lowered, and locked to the lower sash, both sashes being simultaneously engaged against the window frame. An

opening at the upper portion of the window is thus provided. In a similar manner the lower sash may be moved upward, locked to the upper sash, and both sashes engaged against the frame. On the other hand, the sashes may be moved toward each other so .as to provide an opening at the top and bottom of the window and locked to each other engaged against the frame.

lVhile I. have illustrated and described my invention with some degree of particularity, I nevertheless realize that in practice various alterations thereover may be made, and I therefore reserve the right and privilege of changing the form of the details of construction, or otherwise altering the arrangement of correlated parts without departing from the spirit of the invention or the scope of the appended claim.

. Having thus described my invention what I claim as new and desire to secure by Letters Patent is In a sash lock, the combination with an upright rack bar adapted to be secured to the side rail of one sash; of a hollow casing having one flat side and one eunved side and ears at its extremities adapted to be secured upon the top rail of the other sash, its top plate having a transverse opening, inward from its straight side, shoulders at the ends of its curved side, lugs depending from said top plate and from the midlength of bothsides, a washer mounted within the space bounded by said plate overlying said top bar, a bolt Whose upper end is fastened ecagainst the other side of said body, the centrically through the disk and Whose body Whole substantially as described. 10 is loosely mounted in the ooenings in said In testimon whereof I aflix my signature top plate and Washer and is squared between in presence 0 two witnesses.
